Slowly starting to wire things up.
While doing that I made a bunch of tiny tweaks, Finally done with this thing. I will release it with the CAD once I prove/test the offsets are right for the probe and nozzle.

Getting a lot closer now, the screws finally showed up.
Had to tweak one of the front tensioner parts, new prints are almost done. Might even get some belts on this thing.

Looks awesome, love that more CNC’d parts are being incorporated.
Do the M3 bolts fastening to 2020 look a bit out of place. Still considering M4/M5?
Look forward to seeing the compact belt setup.
Those holes are separately set to be sized any way you would like in the parameters tab. Pretty easy. Last time I tried the CAD all worked sizing up and down.
I have belts on one of the truck parts were extruded wrong, so they are reprinting now.
I have to say the belts are pretty good to work with. You can set them pretty tight even just by hand and they are balanced, then you take that centerpiece and set it in the belt groove, and it is perfect. The only part I needed to guide it a bit was the logo hole in the truck, the rest was surprisingly easy to thread through. I might be able to change that up, I need to take a look to see the overhang angle.
Not sure what sort of schedule I have tomorrow, bagging bolts and hopefully doing some XY movements at least…I am extremely pleased with all of this so far. The metal makes that middle X rails extremely solid, it has been a breeze to build.

Before I forget again, didn’t check CAD yet, but hoping rear mounted Steppers have room for some heat sinks (40x40x12mm). The Alu mounts will be great.
That looks really really good. Quick question on the metal parts… would 1/8" aluminum work? I can’t bend it by hand, but 1/4" or 3/16" probably seems more appropriate. I will probably cut one just for the experience of cutting aluminum with the mpcnc since that is one more thing on the bucket list.
I didn’t see any update to the z stops. Did those belt clamps change?
If you print those stepper mounts in something other than PLA you should not need heat sinks, steppers can handle a lot of heat.
The new machine is mounted to aluminum so you can go hot enough to boil your bearing grease if you really want.
There is a dance between, mount thickness, stepper mounting screw length, frame mount screw length, and pulley position. I am using just under 5mm and that is as thin as you can go before you need to flip the pulley then you need to go much thinner. That depends on your stepper shaft length as to ho thick you can go. With my steppers I would not recommend less than 0.187" / 4.75mm.

No, I adjusted them a bit and they seem better, so I think I want to try them this way since they are so simple.

@vicious1 what size bed is that you are using? This is always a big confusion for me for some reason. Is it a true 300mmx300mm or is it 310x310 for a usable 300x300.

Mine is 305x305 for a 300x300 usable with counterbored M3 screws so secure it in that outer 5mm.

Ok good deal. I was looking at premade ones on AliExpress and had me wondering. Thanks!!
I got all this stuff on Amazon a while back, so it looks like the price has moved around a bit.
Bed plate, Amazon.com $27
Insulation, Amazon.com $12
Fuse, Amazon.com $7
Heater, Amazon.com $37
PEI, Amazon.com $50
SSR, Amazon.com $13
The bed stuff alone is $146 -How do they sell printers for $170 (Amazon.com)…blows my mind

lol a lot of that is the same exact parts I have on the V4. And it has all worked real well on there. I was worried about that SSR with how cheap it was but it has done great!
Glad to hear that. Since we are not coming anywhere nears its capacity, I am sure it should stay nice and cool.
Working on a fresh klipper install right now, and documenting the process. I might actually get some movement today!!!
I also tweaked that truck part again last night and reprinting it now, again, that should make installing belts simple.

Also added a bit more to the CAD.

Klipper is real easy if you start off with the example config from klippers site
I think I am comfortable with that part, this whole setting up the pi and skr is new. It is straight forward because of these three videos though, https://www.youtube.com/watch?v=OmBIHB9TFgc. The klipper site install directions are not for me at all. Without KIAUH I would not be doing this for sure.

Really. That is very surprising to me. I’ve done klipper a few times before I ever knew about KIAUH and never had an issue I couldn’t figure out from Google. Biggest part for me was always finding the example config to start with and know what settings to put when I go to make menuconfig lol. The rest of it I just start and when I have a problem I Google till I figure it out and move on to the next problem lmao. Put me in marlin config and it’s 1000 times harder. So much stuff in there that doesn’t apply to my situation and knowing what I need to use and what not to mess with I just get lost lol. I know for klipper everything in my printer.cfg applies to my printer. And if it doesn’t I can delete and get it out of the way lol.
I have spent very little time in a terminal, have no idea what is needed and in what order to do it. That video series though…golden. It has gotten a bit easier since he made those but the KIAUH system is amazing. This is my third time doing it all from scratch and each time I see they are adding more and more options for easy install (mobileraker seems interesting, and maybe telegram?)
I actually agree. Marlin was only easier 10-12 years ago. This klipper method is better, and the config part (like fluidnc) is the way it needs to be done these days, everything in one text file, with all the crazy configs. 10-12 years ago marlin was easier because the config page had every option with descriptions so it was like the Klipper config but better because it listed everything. Now there are just too many options spread over too many pages with too many dependencies you do not know about until the compile fails. Even for me maintaining the marlin config we have is a real drag now.
Side note. Until I met Jeffeb3 I did every marlin release by hand, updating all the options for all the build and boards fresh each time from my notes. Heffe introduced me to git, kicking and screaming the whole way. Without him, we would certainly be running very old Marlin, or I would have quit long ago.
I am pretty sure marlin will make some changes, maybe some sort of marlin3.0 with an updated config system. Hopefully soon.

I am actually probably only running klipper because setting up these printers in marlin now are too hard, take too long, and tuning is a real bear. my last printer I have a list of notes and I did not want to do it all again.
Getting the bed leveling stuff set up is not very easy, let alone the advanced stuff like pressure advance, and accel tuning.
